Grey days: Julianne Moore reports to the Hunger Games set in Atlanta following the death of frequent co-star Philip Seymour Hoffman

In the Hunger Games, President Alma Coin is described as being mono-chromatically grey - uniform, hair, and eyes which appear 'as if almost all the color has been sucked out of them.'

But Julianne Moore had another reason for feeling grey as she reported to the Atlanta set of Mockingjay: Part 2 on Wednesday - the death of her frequent co-star Philip Seymour Hoffman.

The 53-year-old actress appeared downcast as she entered a building while outfitted in the same District 13 costume Jennifer Lawrence and Liam Hemsworth were also seen wearing.
